Description and Introduction

16-Bit 8-/16-Channel Delta Sigma ADC with Easy Drive Input Current Cancellation and I2C Interface The LTC2497CUHF#PBF is a 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 24-bit  
- **Input Channels:** 16 single-ended or 8 differential  
- **Input Voltage Range:** ±VREF (differential) or 0V to VREF (single-ended)  
- **Reference Voltage:** External (supports ratiometric measurements)  
- **Conversion Rate:** Programmable (3.5Hz to 880Hz)  
- **Noise Performance:**  
  - 0.5μVRMS noise at 6.9Hz  
  - 1.2μVRMS noise at 880Hz  
- **Interface:** I²C-compatible (supports standard, fast, and high-speed modes)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 38-Lead QFN (5mm × 7mm)  

### **Descriptions:**  
The LTC2497CUHF#PBF is a high-precision, low-noise ADC designed for applications requiring accurate signal acquisition. It features Easy Drive technology, which minimizes input current and eliminates the need for external buffers or filters. The device supports both single-ended and differential inputs, making it versatile for various sensor interfaces.  

### **Features:**  
- **Easy Drive Technology:** Eliminates input current errors and relaxes drive requirements.  
- **Integrated Oscillator:** No external crystal or clock required.  
- **Programmable Speed/Noise Trade-off:** Adjustable conversion rate for optimized performance.  
- **Rejected Common-Mode Signals:** Excellent 50Hz/60Hz rejection.  
- **Low Power Consumption:** Typically 1.5mA (at 5V supply).  
- **Small Footprint:** 38-lead QFN package for space-constrained designs.  

This ADC is suitable for industrial, medical, and instrumentation applications requiring high-resolution measurements.
